    tree-optimization/109735 - conversion for vectorized pointer-diff

    There's handling in vectorizable_operation for POINTER_DIFF_EXPR
    requiring conversion of the result of the unsigned operation to
    a signed type.  But that's conditional on the "default" kind of
    vectorization.  In this PR it's shown the emulated vector path
    needs it and I think the masked operation case will, too (though
    we might eventually never mask an integral MINUS_EXPR).  So the
    following makes that handling unconditional.

            PR tree-optimization/109735
            * tree-vect-stmts.cc (vectorizable_operation): Perform
            conversion for POINTER_DIFF_EXPR unconditionally.=
